A wheel tractor-scraper is operating on a level grade, assuming no power derating is required for equipment conditions, altitude, and temperature.

Disregarding traction limitations, what is the maximum value of rolling resistance (in lb/ton) over which the fully loaded unit can maintain a speed limit of 15 mph?

Also, What minimum value of coefficient of traction between the tractor wheels and the traveling surface is needed to satisfy the requirements of part A? For the fully loaded condition, 52% of the weight is idstributed to the drive axle. Operating weight of the empty scraper is 74,946 lb.
